1 农田冬小麦真实节水潜力的概述1.1 农田冬小麦真实节水潜力的基本特征农田冬小麦真实节水潜力是指对某农田冬小麦通过节水可能取得的最大真实节水量。其影响因素主要有两个:一是现状条件下的渠系状况及其节水(包括把土渠输水改为管道化输水,进行渠系防渗)所能够减少的无效蒸腾蒸发量;二是现状条件下的田间耗水状况及其节水(包括灌水技术改进,灌溉制度改进,田间保墒技术和生物工程技术的推广等)所能够减少的
A summary of the real water-saving potential of farmland winter wheat 1.1 The basic characteristics of the real water-saving potential of farmland winter wheat The real water-saving potential of farmland winter wheat is the maximum real water-saving can be achieved through water-saving of winter wheat in a farmland. There are mainly two influencing factors: one is the status of canal system and its inefficient transpiration evapotranspiration that can be reduced by saving water (including changing the water from canal to pipeline and seepage control of canal system) Second, the current situation of field water consumption and its water saving (including irrigation technology improvement, irrigation system improvement, field moisture conservation technology and bioengineering technology promotion) can be reduced
